limit_count: 1
rate_limits:
- scope: per-api-key
  limit: 600
  window: 1h
  unit: requests
  burst: null
  default: true
  negotiable: true
  note: >-
    Published as the default limit. The docs invite customers needing higher
    limits to contact support, so the ceiling is contractual rather than fixed.
headers:
  limit: X-RateLimit-Limit
  remaining: X-RateLimit-Remaining
  reset: X-RateLimit-Reset
  reset_format: unix-timestamp
  retry_after: Retry-After
  standard: >-
    Vendor-prefixed X-RateLimit-* rather than the IETF RateLimit-* draft headers.
    Returned on every API response, not only on 429.
exhaustion:
  status: 429
  body: Too Many Requests
  retry_after_present: true
guidance:
  from_docs: >-
    Cache responses where you can and batch period-over-period or multi-asset
    queries instead of fanning out.
method_note: >-
  searched, not probed — every endpoint requires an Enterprise API key, so the
  live headers could not be observed anonymously. Values are the provider's
  published numbers.
